I thought that would be a good place where to record the selection of a different frame.
(Of course, one should restrict it to cases where users select the frame (or create one), rather than temporary selection of the frame through a program.)

Ah sorry, I forgot to show this.  Here's what I meant.

  if (XINT (Flength (Vframe_list)) > 1)
    {
      Vframe_list = Fdelete (frame, Vframe_list);
      Vframe_list = nconc2 (Vframe_list, Fcons (frame, Qnil));
    }

and something equivalent like Fnreverse (Fcons (frame, Fnreverse (Vframe_list)))  does the same and I'd like to understand why.
